PRÓLOGO
Todo es cuestión de nombres. No hay nombre acomodado.
La ciencia.
Juicios lógicos.
La demostración.
Poco valor de los silogismos.
In this early modern meditation, a learned physician‑philosopher lays bare his restless pursuit of genuine knowledge. From childhood curiosity about nature to a growing disenchantment with the conflicting doctrines of his contemporaries, he recounts how every scholarly answer he encounters ends in doubt, leaving him to turn inward and test the world’s phenomena against first principles. His candid reflections reveal a mind caught between the allure of ancient theories—atomism, Platonic ideas, Aristotelian universals—and the stark emptiness he perceives in their speculative webs.
The work unfolds as a spirited critique of the prevailing academic fashions of the sixteenth century, exposing how scholars often fashion elaborate fictions rather than uncovering firm truths. By confronting the “labyrinth of words” that obscures reality, the author invites readers to share his skepticism and to consider a more disciplined, experiential approach to learning. The result is a compelling, almost conversational treatise that challenges the complacency of accepted wisdom while celebrating the relentless drive to understand the world directly.
